Roaming policy and charging control method and system

Abstract

The provided cruise strategy and charge control method comprises: A. V-PCRF receives the authorized query from AGW to obtain application message from AF; B. V-PCRF sets the access strategy and charge rule according to obtained message and local strategy, and sends the result to AGW; and C. the latter executes the strategy and charge control to UE. This invention reduces signaling delay, and improves efficiency.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a roaming policy and charging control (Policy and Charging Control, PCC) method and system. Background technique [0002] With the rapid development of communication and information technology and the maturity of Internet Protocol (IP) technology, the application of Internet (Internet) is rapidly popularized. People are no longer satisfied with a single voice communication method, but need a new multimedia communication method. . At the same time, mobile communication networks and fixed communication networks are still the main ways for people to communicate. Therefore, the IP-based mobile communication networks and fixed communication networks, as well as the integration of the Internet and telecommunications networks, have undoubtedly become the industry's recognized development direction. That is to say, the IP multimedia communication system that can support multipl...

Problems solved by technology

[0019] From the steps described in Figure 3, it can be seen that during the policy and charging control process during roaming, the V-PCRF needs to pass through the H-PCRF of the home network to exchange information with the AF, which can easily cause signaling delays. This in turn reduces the execution efficiency of the policy and billing control process
